About Golang getting IP and MAC addresses on Raspberry Pi

This is a created article in which the information may have evolved or changed.

Objective

Recent jobs needed, demand for Get Raspberry Pi Ethernet IP
Address and MAC address, looked at the next Golang document, found net. Interfacebyname can accomplish this goal.

Realize

        //以太网网卡名称为eth0        inter, err := net.InterfaceByName("eth0")        if err != nil {                log.Fatalln(err)        }        //mac地址        fmt.Println(inter.HardwareAddr.String())        addrs, err := inter.Addrs()        if err != nil {                log.Fatalln(err)        }        //ip地址一个ip4一个ip6        for _, addr := range addrs {                fmt.Println(addr.String())        }

Operation Result:

Postscript

Of course, the Raspberry Pi 3 generation of the wireless network card, the name of Wlan0 can get the wireless network card IP.
